I SKIP FOR RAISING AND STACKING BRICKS.

Application filed December 21, 1927, Serial No. 241,517, and in GreatBritain January 10, 1927.

and stacking bricks and its object is to provide a skip into whichbricks can be loadedby hand and the load of bricks raised in the skipand automatically deposited in a stacked condition. Thus the cost oftransferring bricks, for instance from a ship or barge to a railwaywaggon or a lorry can be reduced by one half, inasmuch as at eachtransfer the bricks have to be handled once only.

The skip according to the invention consists of an open bottomed box orframe of a size to contain without undue clearance bricks stacked inpiled rows and, beneath each row of bricks, a bar temporarily supportedbeneath the middle of each row and so guided, when released from thesupports, as to descend under the weight of the bricks and becomelaterally displaced from thereunder. Thus when supporting bars are nolonger beneath the respective piled rows of bricks, the skip can beraised leaving the bricks piled in rows wherever the skip has beendeposited.

The bars conveniently are round rods.

Preferably and advantageously the disengagement of the bars from thesaid supports is effected automat-1cally,and such disengage mentpreferably is arranged to occur on raising the loaded skip, the barsbeing held from displacement by the hoisting slings.

The ends of the bars for instance are guided in grooves or slotsextending from about the middle line of the respective row of bricksobliquely downwards to clear of one side of the row. The temporarysupport of the bar can be provided by a lateral shouldered downwardlyinclined notch at the upper end of each guide groove, similar to thenotch of a bayonet joint. By the ends of the bars being connected to thehoisting slings, on raising the skip the bars are withdrawn from thenotches, so that on deosit of the skip, the bars can, under the weightof the bricks, descend the guide grooves or slots and become laterallydisplaced from beneath the bricks.

A brick raising and stacking skip operating as above described isillustrated, by way of example, on the accompanying drawing, in whichFig. 1 is a side elevation of the skip, the brick-supporting bars beingshown in section, and

Fig. 2 is a. corresponding plan.

Fig. 3 i a s de e evation showing the end ofv a supporting bar and aportion of the giude groove therefor, and

' Fig. 4 is a corresponding sectional view, both on a larger scale.

Fig. 5 is an elevation of gravity catches separated by and about toengage the sling bar, shown in cross-section.

The skip is constituted by an open' bottomed box a: divided by twomutually adjacent partitions b, 6 into two compartments each of a widthto accommodate, with ample clearance, two rows of bricks c.

Each row of bricks c is supported on a bar 0? extending from one side tothe opposite side of the skip an, the ends of the bars d protrudingoutwards through guide slots 6 in the respective sides of the skip a.

The guide slots 6 for the ends of the bars (1 extend from about themiddle line of the respective row of bricks c obliquely downwards toclear of the side of the row. Thus the slots 6 beneath the two outerrows of bricks extend beneath and to beyond the outer end walls f of theskip a, whilst the slots 6 beneath the two inner rows of bricks extendbeneath and to between the two inner partitions b, b.

At their upper ends the slots e have recurved downwardly inclinednotches e which provide lateral shoulders for the temporary support ofthe bars (l whilst the bricks c are being stacked in the skip a andprior to raising the loaded skip.

A low partition 9 is provided between the outer and inner rows of bricksto hold the lower layers of the bricks from canting on the supportingbars d.

' The ends of the supporting bars d have eyes 72, journalled thereon andsecured at each end by a nut 11 with interposed washers, as shown inFigs. 3 and 4.

On each side of the skip a, the eyes h are connected by lengths of chain7' to eye holes in formed in a yoke bar Z, which is loosely held andfreely guided between angle guide bars m vertically secured to the sidesof the skip a.

The yoke bars Z are respectively connected by chains n extending fromeye holes 0 therein to the respective end of a transverse sling bar p,which extends transversely across the skip a in the space between thetwo middle partitions b, b, the ends of this bar 2 protruding throughthe sides of the skip through a vertical slot 9 in each side.

Rings r extend. ugh hole in the tra verse sling bar 7) for theattachment of the slings of a crane or other hoisting contriv- Thebricks are, as shown, stacked in the skip with the bars cl supported inthe bayonet notches of the guide slots 6.

On hoisting the skip by means of slings secured to the rings 9, thesling bar p is raised towards the position shown in dotted lines 79 inFig. 1 and by the chains it raises the yoke bars Z on each side in theirguides 911-, until, on the entire slack of the chains being taken up,the brick-supporting bars d are raised out of the bayonet notches 6 intothe upper ends of the guide slots 6. Continued hoisting raisesthe skip athrough the brick-supporting bars (Z.

On thereafter lowering the skip a on to a surface, the chains 0nslackening permit the rows of bricks to depress the bars (5 along theoblique guide slots 6 eventually to beyond the end walls 7 and innerpartitions Z) respectively of the skip.

The sling bar 39 on being drawn down wards by the weight of the bricksbearing on p the bars (Z, is engaged by pivoted gravity catches 8. Thesecatches s are thrust aside by the descending sling bar 7) and, under theinfluence of their weighted lower ends, engage by their hooked upperendsover the sling bar 29. The skip thereupon can be hoist-ed by thesling bar p, without the sling bar p being raised in the vertical slots(1 and without the chains 12, raising the bars (Z in the oblique slots6, so that the bricks are left stacked in rows deposited on the surfaceon to which the skip was lowered.

The sides of the skip a transverse to the rows of bricks o are suitablycut away as shown to provide easy access to the interior forfacilitating placing thebricks in position by hand. 7'

The skip may conveniently be constructed to hold one ton of bricksarranged as shown in four piled rows with the individual bricks in eachrow arranged with their 9 dimension transversely to their supporting barand their l dimension vertical.

Claims:

1. A skip for raising and stacking bricks, consisting of an openbottomed box frame, and a bar in said frame, said frame being formedwith downwardly inclined notches beneath the middle of a row of bricksin said frame and with slots guidin said bar and extending obliquelydownwards from said notches to and clear of one side of said row.

2. A skip for raising and stacking bricks, consisting of an openbottomed box frame, a bar in said frame, said frame being formed withdownwardly inclined notches beneath the middle of a row of bricks insaid frame and with slots guiding said bar and extendobliquely downwardsfrom said notches to and clear of one side of said row, and means forslinging said frame by said bar.

3. A skip for raising and stacking bricks, consisting of an openbottomed box frame, a plurality of bars in said frame, said frame beingformed with downwardly inclined notches beneath the middles of rows ofbricks in said frame and with slots guiding said bars and extendingobliquely downwards from said notches to and clear of one side of eachof said rows, means for slinging said frame by said bars, and gravitycatches on said frame engaging said slinging means when loweredrelatively to said 'rame.

In testimony whereof I have signed my name to this specification.
